Microstructure and High Temperature Oxidation Resistance of Modified Aluminide Layer on γ-TiAl Alloy Surface by Powder Packing Cementation Method
摘 要
采用粉末包埋渗金属技术在γ-TiAl合金表面制备出一层渗铝改性层, 对改性层的表面形貌、元素分布规律及相组成进行了检测与分析, 并试验研究了改性层在850 ℃静态空气中的抗氧化性能。结果表明: 改性层均匀致密, 无明显的贯穿裂纹, 主要组成相为TiAl3; 在850 ℃静态空气中恒温氧化100 h后, 表面氧化层主要由Al2O3、TiAl3、TiAl2相组成, 改性层显著提高了γ-TiAl合金的高温抗氧化性能。

Abstract
The surface modified aluminide layer on γ-TiAl alloy was prepared by powder packing cementation method. The surface morphology, element distribution and phase composition of the modified layer were tested and analyzed. The high-temperature oxidation behaviors of modified aluminide layer at 850 ℃ in static air were studied in experiment. The results show that the aluminized layer was uniform and compact, had no obvious penetrating cracks and consisted of TiAl3. The modified layer after oxidation at 850 ℃ in static air for 100 h was mainly composed of Al2O3, TiAl3, TiAl2 phases. The high temperature oxidation resistance of γ-TiAl alloy was improved obviously due to the modified aluminide layer.
